When I lived in British Columbia for a few years in the bush I had no running water or electricity so makeing fires were a way of life for heating water and food being outside on the pitfire or on the wood burning stove, so I always smelt like a camp fire and personally I think it is one of the best cover-up scents ever made. I have stalked up on a lot of moose, elk and mulies smelling like a campfire. The real secret is to hunt with the wind in your favor, but its difficult at times, especially when the winds change on the hour, but I do think that it will buy you some time. Even here in Montana I do a lot of my hunting in the burns that were here a few years ago and the soot smell still lingers and by the end of a day hunting and stalking through there, I myself smell like soot at the end of the day.
